I FIG. 4 is a somewhat smaller view of the rear surface of a slider, diagrammatically illustrating the bulged contour of the compressed wall. I FIG. Sj is:a diagrammatic view, illustrating the manner 'of positioning and assembling sliders with a pair of stringers in accordance with the teachings in FIGS. 2

FIG. 6 is a view, similar to FIG. 1, of a modified form of'slide r, illustrating two broken away portions and omit- :tingpart of the slider structure. I 1 a I view, generally on the broken FIG. 7 is a sectional FIG. 6, omitting background showing; and

FIG. 9 is a view, similar to FIG. 2, showing only part of the construction and showing a modification.

In FIGS. 1 to 4, inclusive, I have shown at 10 one form of slider made according to my invention, the

slider comprising walls 11 and 12 joined and'spaced by a connecting web 13, the wall 11 only having side flanges 14 for'guidance of the scoops 15 of a pair of stringers 16,

note FIG. 3, into and out of the channel 17 of the'slider body, as with other devicesof this type and kind.

The wall 11 includes. at end portions thereof, projecting platforms 18 and 19, having integral rivet forming portions 20, 21 for retaining the plate or yoke 22 upon the platforms, with the rivets flush with the outer surface of 22, as clearly seen in FIG.'2 of the drawing. It will clearly appear, from FIG. 2 of the drawing, that the'platform 18 is lower than the platform 19, so as to receive and support a spring'lock 23 having a protruding lock element 24 at the terminal end thereof. Considering FIG. 1

3,170,208 1 Patented Feb. 23, 1965 set to one side of the lock 23, but any desired arrange- 'ment of this element can be provided. In order to increase the spring properties of the lock 23, the end portion thereof is provided with an elongated aperture 25, as clearly noted in FIG. 1 of the drawing, this aperture forming side arm portions 26.

The wall 11 has a transverse aperture 27 therein, in which the free end portion of the lock 23, including the element 24, operates. The aperture 27 has a bevelled wall 28 which extends onto a raised cam lug or member 29, including a bevelled surface 30, upon which the rounded pivot end 31 of a pull 32 operates in movement of the lock 23 into inoperative position, in other words, with the element 24 out of the channel 17 of the slider body in providing free movement of the slider along the scoops 15 in the operation of separating the stringers 16. In the reverse operation of the slider, the element 24 will ratchet over the scoops 15, as with other devices of this type and kind. The pivot end portion of the pull 32 has an elongated aperture 33 to allow the pull to drop onto the wall-11 with the pull in either direction on the slider.

Turning now to the showing in FIG. 9 of the drawing, in this figure, 10' represents a slider body modified from the showing in FIGS. 1 to 4, inclusive, to the extent of providing a wider'spacing between the platforms 18' and 19 and to positioning a stop member 29, similar to member 29 of FIGS. 1 and 2 in wider spaced relationship to the platform 18, so as to provide on the wall 11 a long surface 34, upon which the rounded pivotend 31 of a pull 32 operates. With this construction, the shape of the lock element 23' is modified to provide a rounded end portion 35 terminating in a lock element 24', generally of the type and kind shown in FIGS. 1 'and2. In this construction, the surface 28 is formed primarily on the wall 11' and does not extend continuously onto the member 29 in the bevelled form, as shown in FIG. 2 of the drawing. In FIG. 9, the normal position of the pivot end 31 is indicated in dotted lines. However, when the pull is advanced to the full line position in moving the element 24 into inoperative position, as shown in full lines in FIG. 9, the lock' element will be retained in hold-open position by engagement of 31 with the surface 34-. Howsimilar to the dotted line position, the spring lock 23' will be automatically moved into the dotted line positionof FIG. 9 to operate'to lock the slider against movement on the stringers; In FIG. 9, the plate or yoke is shown at 22' and one of the flanges on the wall 11 is indicated at 14 -.w Aside from the foregoing,- thestructure of the slider of FIG. 9 will be the same a's that shown in FIGS.

l to 4, inclusive.

Considering now FIGS. 2

when a separable fastener is positioned within the wide- "stringers within the channel, as will appear from the dotted line showing of the scoops '15 and-stringers 16 in FIG. 3 of the drawing and after the scoops and stringers have assumed the full line position of FIG. 3, a compression tool 35, having a contour portion, as indicated at 36 in FIG. 2, is actuated to force the wall 12 from the dotted line position to the full line position in FIGS. 2

, and}. In this operation-, the slider body is supported in of the drawing, it will appear that the element24 is off a suitable backing or nest, as indicated in dot-dash lines at 37 in FIG. 2, the nestbeing omitted from the showing in FIG. 3. Upon completing the compression operation described, a raised mound 38 will be formed on the wall 12 in alinement with theweb 13 and the general contour of this mound, as viewed from the rear of the slider body, is diagrammatically outlined inFIG. 4 of'the drawing. The mound 38 is formed'as the wall 48 is moved and 3 of thedrawing, the i slider, as originally formed, will have the walllZ in the dotted line position indicated in these figures and, then,

a is

toward the wall 47 during the compression of the slider blank. The metal at the right side of the web as seen in FIG. 2 flows into the cavity 36 to form the mound 38.

In order to diagrammatically illustrate the method of procedure, the pairs of stringers 16, including the scoops 15, are diagrammatically illustrated in FIG. 5, with the bottom stops of long lengths of stringers being illustrated at 39 and the top stops being illustrated at 40, 41 representing the spaced portion of the stringers between each stringer length in the automatic production of fasteners of the type and kind under consideration.

In FIG. 5, 16" diagrammatically outlines a slider, such as shown in FIGS. 1 to 4, inclusive, which can be positioned on the coupled stringers by movement in the direction of the arrow 42 of FIG. '5 when the wall 12 of the slider is in the dotted line position, as in FIGS. 2 and 3, after which the compression operation takes place in positively coupling the slider with each stringer length.

With my improved slider structure and by virtue of employing the plain or unflanged wall 12, it will be appareat that the compression of the wall 12 is minimized by yirtue of spacing of the inner surface 43 from the dotted line showing in FIG. 3 to the surface 4-3 on the full line showing of the wall 12 in FIG. 3. In other words, the surface 43 is so spaced with respect to the surface 44 of the flanges as to provide free admission of the coupled stringers between the surfaces 43 and 44-, as will clearly appear from a consideration of FIG. 3 of the drawing. This compression movement is materially less than that which would be required as and when both walls of the slider body are flanged. From this standpoint, it will be understood that, in some instances, the slider can be positioned on the stringers by movement across the stringer tapes or, in other words, in the direction of the arrow 45 of FIG. 3 of the drawing.

Turning now to the showing in FIGS. 6, 7 and 8 of the drawing, in these figures 46 shows a modified form of slider body, having spaced walls 47 and'48 joined and spaced by a connecting web 49. The wall 47 has spaced platforms 50, 51, generally similar to the platforms 13, 19' of FIG. 9. The wall 47 includes side flanges 52,

which differ from the flanges 14 in including bevelled.

shoulder portions 53, the purpose of which is solely to guide specially contoured scoops through the channel 54 of the slider body, as will appear-from a consideration of FIG. 8of the drawing.

The slider body 46 differs from the body in that the web 49 has an .abruptly contracted inner end, as indicated at 49 in FIG. 6 of the drawing. Further, the wall 47 has a longitudinal rib 55, generally. of the crosssectional form illustrated in FIG. 8, the rib tapering in the direction of the contracted end of the slider body. The wall 48 has a similar rib 56; these ribs, in addition to adding strength to the slider body, further conform to and guide special type of scoops through the channel of the slider body. The slider body 46 is further modified to the extent in providing spaced apertures 57, S8 in the is indicated at 73.

stringer.

bevelled walls being clearly shown in FIG. 7 of the drawing. These walls 65 form guides definitely locating the reduced end of the spring lock 61 in alinement with the apertures 57 and 58. This end of the spring lock includes a crosshead 67, clearly shown in FIG. 8 of the drawing, which will seat upon the upper surface of the wall 47 in checking inward movement of the elements 59, 60 or, in other words, movement into operative position, as indicated in dotted lines in FIG. 8 of the drawing, with said elements projecting into the channel 54 of the slider body. As with the structure shown in FIGS. 1 and 2, the spring lock 61 is apertured intermediate its ends, as indicated at 68 in FIG. 7, to control tension of said spring lock.

' At 69 I have shown the rounded pivot end of the pull 7%, generally similar to the pull 32 shown in FIGS. 1 and 2 of the drawing. The pull has an elongated aperture 71 to clear the platforms in swinging movement of the pull in both directions on the slider body. In FIG. 7 or" the drawing, the pull is shown with the pivot end 69 supporting the spring lock 61 with the elements 59 and 66 in ino erative osition, or in the full line osition of FIG. 8 and, in this position, the spring lock 61 is retained in a hold-open position by arrangement of 69 on the surface 72 of the wall 47 in a manner similar to the hold-open position, as noted in FIG. 9 of the drawing. However, in upward movement of the pull, as viewed in FIG. 7, the spring lock 61 will be released and the elements 5? and 60 will automatically move into the oprative position, as indicated in dotted lines in FIG. 8 of the drawing.

Considering FIG. 7 of the drawing, it will appear that inner edge portions of the wall 48, in alinement with the web 49, are bevelled for free guidance of the scoops into the channel of the slider body and one of these bevels In this figure, I have also shown at 74 the bulge on the wall 43 as a result of moving this wall from its normally formed position to the operative .positionfor engagement with the scoops of the stringers. This bulge '74 is formed as is the mound 33 during the compression'operation for attaching the slider to the lnother' words, the wall 48 would assume a spaced position, generally similar to the dotted line position of the wall I2 in FIGS. 2 and 3 of the drawing, and the'fuil line position of the waii 12 in said figures is comparable to the showing of the wall 48 in FIGS. 7 and 8 of the drawing. It is pointed out, at this time, that the ribs, as at 55, 56, do not interfere with attachment of the slider-with coupled stringers in the manner illustrated in FIG. 5 of the, drawing, as these ribs fit in grooved or "recessed portions between adjacent coupmd scoops-at upper and lower surfaces thereof, which is a characteristic of the scoops for which the slider shown in FIGS. 6 to 8 inclusive is constructed.

By employing the two apertures 57 and 58, as seen in FIGS. 6 and 8 of the drawing, it will appear that the rib 55 extends fromthe web 49 longitudinally of the wall wall 47 rather than the single aperture 27, as noted in FIG. 1, these apertures providing free movement of two lock elements 59 and of a lock spring 61, the spring being fixed to the platform 50 by the integral rivet 62, generally similar to'the rivet 20, which secures the plate or lug 63 to the platforms, the other rivet, for this purpose, being indicated at 64, which is generally similar to the rivet 21. For sake of clarity, the spring lock 61 and its components are omitted from the showing in FIG. 6.

The lock elements 59 and 60 are spaced at sides of the free'end of the spring lock 61 to register with and operate in the apertures 57 and 58, respectively, as will appear from a consideration of FIG. 7 of the drawing. For simplification in the illustration, the spring'lock 61 and the elements 59 and 60 are omitted from the broken away portions of FIG. 6. ''Part ofthis broken away portion will show raised side walls on the wall 47 terminating at their ends in be'velled'walls 66, one of these 47 without a break therein, thus providing a smooth nonraspy operation of the slider over. the separable fastener chain. I g

It willbe apparent from the foregoing that the slider 7 made in accordance with my construction will have limited overall thicknesses, thus producing what I term thelow silhouette contour. This is advantageous from the standpointof' general use of the, slider in operation of the fastener and, further, from the standpoint of subjecting the apparel to which the fastener is attached to laundering operations.
